The Seca II is the name the air-cooled XJ 600S Diversion carried in North America and Australia. It replaced the older XJ600/FJ600 with a retuned 599 cc four that favoured low and midrange pull over peak power, topped by a small bikini fairing. It was a cheap, durable, easy-riding commuter and learner-friendly middleweight, and the US version ran until 1998.
